I installed with the choice of Cinnamon, but would like to try other desktops. I imagine that it could be as easy as selecting them from the display manager, but am curious about the installation of a particular desktop, and how it may affect my installation. I have yet to install any deepin packages. I thought I would check here first just in case there may be issues. I hope this is the proper forum.

Does my installing of it negatively affect my current set up in any ways? By that, I mean does it damage my Cinnamon set up?

I am kind of new at experimenting with desktops, so I hope you can forgive what might be a dumb question. I am just paranoid a tiny bit.

I have never done it, so I cannot take parts on this. But it was a good chance to do some searching. Actually, the advice I saw given is that there is no risk messing with different libraries since there are already installed mixed packages.
The only drawback mentioned was unnecessary dependencies pulled in which take up disk space (which is cheap nowadays, anyway)…

another option until we figure out the correct way to install virtualbox is to just go to another distro that has that DE in Live CD. then you can sample without installing anything. of course you wont get the custom Antergos look for each one but if will give you an idea on how the DE works and feels.

I’ve been using Antergos with Gnome and Cinnamon for more than a year and I experienced no problems, as these 2 DEs share many common files. I would not create separate users for each DE as this may compromise file sharing.

So, for some it works for some not. I was thinking that the digital world was 0 or 1, yes or no, but there seams more going on then we know.
Is there somebody that has experience with switching between Gnome and LXQt?
